The project launched on June 15 when a selection of BT ArtBoxes were on display in Trafalgar Square for the day. From June 18 to July 16, BT ArtBoxes are showcased across London’s streets and landmark locations, such as Covent Garden, St Pancras Station, Carnaby Street, Hyde Park and even the shark tank at the London Aquarium (location map). Then, all the boxes will be auctioned off through eBay and Sotheby’s to raise money for ChildLine’s 25th anniversary (more info). London has hosted similar charity art projects helped by celebrities and creators every now and then, such as the Black Dog Campaign, the Big Egg Hunt, and the Elephant Parade.
